Abstract: Methods for arc detection in a system including one or more photovoltaic generators, one or more photovoltaic power devices and a system power device and/or a load connectible to the photovoltaic generators and/or the photovoltaic power devices. The methods may measure voltage, current, and/or power delivered to the load or system power device, and the methods may measure voltage noise or current noise within the photovoltaic system. The methods may periodically, and/or in response to detecting noise, reduce an electrical parameter such as current or voltage in order to extinguish an arc. The methods may compare one or more measurements to one or more thresholds to detect arcing, and upon a comparison indicating that arcing is or was present, an alarm condition may be set.

Abstract: Methods are described for monitoring a power grid at an output of a power converter. Operational parameters of the power converter may be determined as a result of data collected during monitoring. A grid code for the power grid to which the power converter is to be connected may be received subsequent to the collecting. An operational mode of the power converter may be established, based, at least on part, on the operational parameters and the grid code. In the event the grid code and the operational parameters match, the power converter may be activated for electrical power production based on the operational mode. When the grid code and the operational parameters do not match, an error condition may be raised.
